Title: Nonlinear behavior of axions
Description: In this talk I begin by reviewing how dark matter axions can undergo Bose-Einstein condensation and why this is captured by classical field theory. I explain that such condensates are spatially localized clumps, as they are organized by gravitation and self-interactions, and they may populate the galaxy. I discuss both the ground state and finite angular momentum states. I then discuss the possibility of parametric resonance of these axion clumps into electromagnetic waves, which may leave an astrophysical signature. Also, I comment on using ultra-light axions to resolve the core-cusp problem at the center of galaxies. (3:30 PM - 5:00 PM, 726 Broadway, 940, CCPP Seminar)
